Hello all! I just got myself a used S9 through my new provider recently (as in a few weeks ago, and it's a joy of a phone so far. But...the Samsung brand earbuds that fit the jack of my previous phone--a LG X-Charge--don't fit the input jack. As far as I know, it's a standard 3.5mm jack, as was the previous phone, but the earbuds' input simply slides in and doesn't grip or stay plugged in, and it won't connect properly. Is it a matter of jack size, or...? I'm puzzled, and I'd appreciate some input. Thanks, y'all!
